Common Signs You Need to Switch to Tankless

Many property owners wait for a total system failure before considering an upgrade, but there are several indicators that your current water heating setup is no longer meeting your needs. Transitioning to a tankless model can offer significant benefits in terms of reliability and physical space.

  • Running Out of Hot Water: If your family has to schedule showers to avoid cold water, your current tank is likely undersized or failing to recover quickly enough.
  • Rusty or Cloudy Water: Discoloration in your hot water often points to sediment buildup or internal corrosion within an aging tank system.
  • Frequent Tank Leaks: Moisture or pooling water around the base of your heater is a major red flag that the structural integrity of the unit is compromised.
  • High Monthly Utility Costs: Older tanks must constantly reheat water to keep it warm, which uses significantly more energy than an on-demand system.
  • Age of the Equipment: Most traditional tanks last about a decade; if yours is older, a replacement is often more cost effective than repeated repairs.

Recognizing these signs early allows you to make a planned transition rather than dealing with an emergency. A modern system provides a fresh start with updated technology that is built to last much longer than traditional models.

Advantages of Tankless Water Heaters

You may be wondering if tankless water heaters really have that much more advantage over traditional water heaters. Besides heating water more rapidly, what else do these tankless wonders do?

Benefits of tankless hot water heaters include:

  • Precision in amounts of water heated – Since the tankless heater’s coils can instantaneously heat water, you no longer have to heat entire, massive tanks.
  • Dramatically reduced energy usage – A tankless heater does not have to be continuously heated, and only operates when you need it. This saves up to 34% more energy than traditional heaters.
  • Compact size – Since the coils are much smaller, and because you do not need to fill large tanks of water at a time, a tankless unit is much more compact and easy to store in smaller spaces.
  • Ensured safety – A traditional water heater needs to be turned off if you are leaving for extended periods of time in case of leaks and flooding. A tankless heater eliminates this issue and protects your property’s safety more efficiently.

The high efficiency of tankless heaters helps maximize savings while contributing to environmental sustainability. With lower energy consumption comes reduced greenhouse gas emissions. Furthermore, they offer long-term value; although the initial investment might be higher than traditional models, reduced operational costs contribute to substantial savings over time. These units often have a longer lifespan, requiring less frequent replacements.

FAQs About Tankless Water Heater Installation in San Jose

How much space can I save with a tankless unit? 

A tankless unit is about the size of a small suitcase and is typically mounted on a wall. This frees up the significant floor space previously occupied by a 40 or 50 gallon tank. Comfort Energy, Inc. can help you reclaim that space for storage or other uses in your home or garage.

Do tankless water heaters provide instant hot water? 

While they provide endless hot water, it still takes a moment for the water to travel from the unit to your faucet. However, once the warm water arrives, it will not run out, no matter how many people need to use the shower or appliances simultaneously.

Is my current gas line sufficient for a tankless system? 

Tankless units require a higher burst of energy to heat water instantly. Our technicians at Comfort Energy, Inc. will evaluate your current gas line during the assessment. If an upgrade is needed, we can handle the technical adjustments to ensure your system operates safely and effectively.

How long do tankless water heaters typically last? 

With proper care, a tankless system can last 20 years or more, which is nearly double the lifespan of a traditional tank. Because we offer a 100% satisfaction guarantee and excellent warranties, you can feel confident that Comfort Energy, Inc. is providing a long term solution for your home.
